[LNMP] Nginx access_log Daily Rotation

Previously, I had a service using Nginx as a reverse proxy. Due to the high volume of traffic, I wanted to do some simple access statistics at the Nginx layer. I found that Nginx’s default access_log writes everything to a single file, which is very inconvenient. After some research, many people suggested using shell scripts to solve this problem. Finally, I found a better solution – Nginx supports the following configuration:

server {
 listen 8082;
 server_name your ip;

 if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})"){
 set $year \$1;
 set $month \$2;
 set $day \$3;
 set $hour \$4;
 set $minutes \$5;
 set $seconds \$6;
 }

 access_log logs/8082_$year-$month-$day.log;
 error_log logs/8082.error;

 # Forward all requests
 location / {
 proxy_set_header Host $host;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_pass http://localhost:8082;
 }
}
